If you're not accomplishing the things you want to achieve in your life, it's time to take a good, long look in the mirror. While it's easy to blame your circumstances-- or other people-- for your lack of achievements and productivity, the one thing that most commonly holds you back is yourself.

Take a look at some self-sabotaging behaviors that may be preventing you from obtaining the success you desire:

Laziness. Let's face it: some people are just lazy. Are you one of them? Laziness doesn't always present itself as a couch potato who sleeps until noon every day. Sometimes, laziness simply means being stuck in a dead-end routine that's leading nowhere. Taking the easy way out is often the comfortable choice, but it's rarely the road that leads to success.

Inability to stay focused. If you find it difficult to get through a task without getting sidetracked, you're probably lacking focus. How many times do you start a project and then take a "quick" break that inevitably leads to updating your Facebook status, reading blog posts, and scrolling through Instagram? Look- we all need mental breaks from time to time. But hold yourself accountable when you start to lose focus.

Fear of failure. No one enjoys rejection. But allowing the fear of failure to hold you hostage is a surefire way to avoid real success. Will you fail sometimes along the way? Absolutely. But you won't ever accomplish anything if you never try in the first place. Remember: failure isn't the end of the road. You're only finished when you quit.

You're a complainer. Have you ever met someone truly successful who whines and complains all day? Doubtful. Stop feeling sorry for yourself. Whatever problems you have are not unique and chances are, someone else has it worse than you do. Instead of complaining about your situation, work hard and change it.

You rely on past achievements. Maybe you were the high school valedictorian, homecoming king, and quarterback of the football team. Perhaps you were the president of your college fraternity and managed to graduate with a 4.0 GPA. Impressive accomplishments, yes-- but once you enter the working world, no one cares about your glory days. Show them what you can accomplish now instead of telling them about what you accomplished then.
